The cookie contains rid and contextcsn

my $cookie = 'rid=123,csn=20100111155236.576336Z#000000#000#000000';

my $req = Net::LDAP::Control::SyncRequest->new(
                 mode => LDAP_SYNC_REFRESH_ONLY,
                 critical => 'TRUE',
                 cookie => "$cookie" );

my $mesg = $ldap->search(
                 base => "$base",
                 scope => "$scope",
                 control => [ $req ],
                 callback => \&searchCallback,
                 filter => "$filter",
                 attrs => ["$attrs[0]","$attrs[1]" ]
                );
